Merged
Conversation
- Add local claude-code package in nix/claude-code/ - Mirror upstream nixpkgs package definition - Add update.sh script to sync from nixpkgs or npm - Add nix/update command for easy dependency updates - Add GitHub Action to auto-create PRs for new versions This allows staying current with claude-code releases independent of nixpkgs update cycles.
